Maxtor External HD 500GB not recognised anymore ; repair

My iMac doesn't recognise the external HD anymore. It appears in disk utility but all buttons are clicked out. I can't verify or repair it. Can anyone give advice a to how to retrieve the data from the disk. Very many thanks.

So you're experiencing the same problem with both your MacBook Pro and your iMac? As you stated it doesn't work "anymore", I take that to mean that it did work at some point.
Is there any chance you can provide the model or specific name of your external drive? I think Maxtor external drives are usually some generation of OneTouch. Also, let us know how you are connecting to the drive (USB or Firewire).
Do you happen to have access to a PC that you can connect it to? If you do, try that. Just a WARNING... if you try to connect it to a PC and it is formatted for a Mac, the PC will say it doesn't recognize the drive and ask if you want to format it... DON'T say yes! We really just want to see if the PC sees it. If it does, you can just disconnect it.

My Time Machine external hard drive is not recognised anymore under 10.9.1

Hi,
I am running 10.9.1 on my MBP13" mid 2010.
I plugged in my external hard drive (Western Digital Elements 500GB portable drive) and it is no longer recognised.
This has been going on for a couple of weeks.
TM says its not connected.
Icon not on desktop
not seen in disk utilities.
I have tried it on another machine (iMac 2006 10.6) and it is not recognised either.
Tried rebooting with the drive plugged in and without.
attempted to install WD Quick Formatter and this saw the drive but was unable to reformat as it said that it was 'in use'
I thought that this might be TM so I disassociated it from TM - Still No Go.
Any Ideas appreciated.

You don't have to do anything.
When Time Machine is out of room, it will automatically delete the oldest backup(s) to make room for new ones. If you have the +Notify after old backups are deleted+ box checked in Time Machine Preferences > Options, you'll see the message in the blue box in #C4 of [Time Machine - Troubleshooting|http://web.me.com/pondini/Time_Machine/Troubleshooting.html] (or use the link in *User Tips* at the top of this forum).
If you do want to manually delete some backups, you can do that, but only via Time Machine. See #12 in [Time Machine - Frequently Asked Questions|http://web.me.com/pondini/Time_Machine/FAQ.html] (or use the link in *User Tips* at the top of this forum).

Seagate Desktop 500GB External Drive USB not recognised

When connecting this drive to either a PC running XP Pro or a Mac (MBP) running OS X 10.5 (Leopard) then I can access the drive without a problem. However, when I connect the drive to a Mac running OS X Server 10.6.2 (Snow Leopard Server) then the drive is not recognised. It does not even show up in the Mac's Disk Utility. I am able to connect USB Flash drives and other USB devices to the same Mac (a new Mac Mini 1TB server to be precise) which verifies USB connectivity.
It looks like there is a compatibility issue with OS X Snow Leopard. Do you work with Seagate at all to correct this issue? is there a firmware/OS X fix?

Have you contacted Seagate, as they manufacturer the hardware? Do they have any updated drivers or firmware or statement of compatibility regarding Snow Leopard on their website?

Hp external hard drive not recognised hp by pc

I have had my HP PC for some time and had never completed a back up so purchased a HP external harddrive. Part-way through the backup process (an hour or so later) the pc displayed a "backup failed" message.
I have since attempted to connect the external HP 500GB passport harddrive to my HP pc and also to other PC's and Laptops in the house, however, eventhough the light comes on the external hardrive once connected to a PC it is not indicating that it is attached the the computer and the drive is not discoverabale.
The external harddrive is useless in its current state and can not be used for anything, and I have yet to successfully complete a backup of my PC. Do I need to buy another external hardrive and start again? and what can I do with the original harddrive so it is recognised by a PC?

I understand your HP external hard drive is not working on any PC you connect it to. If I understand correctly, the drive is not listed in Computer where other drives are listed.
With the drive connected, go to Start>right-click computer>manage. Select disk management on the left of the new window that opens. Disk management will have a list of detected drives and a visual diagram of the detected drives as well. If possible, please upload a screenshot of disk management. Screenshots can be added by clicking the photo icon and browsing for it on the PC.
What model is the external HDD?
Has a different USB cable been tried? The cable might be providing a good connection for power, but not necessarily for the data connection as these two functions rely on different pins. Just don't want to overlook something as simple as a faulty cable. If you don't have one to try with, then don't buy one just yet as I would like to see what disk management shows.
I'll keep an eye out for your reply.

External ASUS VE228H not recognised by Win 8.1 on new HP Envy 17 Notebook

Hi, I'm new to the forum so apologise in advance if I'm a little technically incompetent. I have viewed other similar posts on this forum but none seem to have the same specific issue that I'm facing.
I have just bought a new HP Envy 17 and am attempting to connect two external ASUS VE228H monitors, one via a direct HDMI cable and the second to a USB port via a UV +39.
Cables and monitors all work fine on another laptop but the new computer does not recognise the two monitors at all. The Intel(R) HD Graphics driver is up to date, as is windows but still in the Screen Resolution area, they do not appear. I have also been through the process of uninstalling, cleaning (via Displaylinks 'Cleaning Tool') and re-installing the Displaylink driver but still not luck.
Via BIOS, I have also tried to (each separately) - 1) Enable Legacy Support 2) Disable Secure Boot and 3) Reset to Default settings all with monitors plugged in and powered on. Unfortunately still no luck. I also checked for any External Monitor settings in BIOS and didn't see any.
Extremely frustrating! Please could someone help?
Much appreciated and thank you in advance.

External hard drive not recognised in start up options

Hi! I'm struggling to get to grips with creating a bootable external drive - any advice would be very welcome!
I've recently bought a LaCie Triple Interface 300GB external drive to use for backup storage and to use as a back up bootable drive should disaster strike. It's connected to my Mac via the FireWire 800 port.
I've backed up my documents and cloned system folders and apps using Intego Backup, but the drive is not recognised in the start up options of the system preferences, nor does it appear as a bootable drive when I option-restart.
Do I need to format and partition the drive before it will be recognised as a bootable drive? (I haven't done so) Or have I just cloned the wrong thing?! I'm not entirely sure what I need to clone to be able to boot and back up from it. Should I clone the entire HD?
Or does it sound like something else entirely?
Can anyone help??
1.8 GHz PowerPC G5 6.5MB RAM Mac OS X (10.2.x)

I'm not familar with Intego Backup. Get Carbon Copy Cloner and use it to clone your entire drive, user files and all.Be sure to check the "make bootable" box before you start the process. Could be that Intego isn't capable of making a drive bootable.

1tb external WD not recognising anymore

Hi
I'm currently using an iMac (2011) running OS X Mavericks 10.9.2.
I've been using a 1tb WD My Passport external hard drive for about 6months. The hard drive has worked fine before with this imac, my brother's macbook air and our PC. I updated to 10.9.2 today and my hard drive doesn't seem to connect to my imac anymore (i've yet to ask my brother when he updated his). The hd still works with the pc. Any chance of a solution?
Many thanks.
-Update- I've asked my brother and he has updated his mac air to 10.9.2 today aswell. I'm presuming it's a software fault/error?

doubt it
had an external 1tb wd hd and it started acting up
in the end it would not work at all
I opened the external box and took out the hd itself and put it in another ext enclosure and there it worked fine so wd was better at making harddisks then at making the external boxes's assume it was an issue with the psu
as it made sounds like it was not getting enough power for the hd to spin up correctly

External Hard Drives not recognised

I have a few different external hard drives on which I have stored photos and movies etc. I used to keep them attached and on all the time, but decided some time back it might be better to leave them off until required. I now have OSX 10.5.8 on my Mac Pro and Macbook Pro and neither will recognise my external hard drives. 1 is a LaCie and the other a iOmega.
Have tried a reboot on both machines with the drives switch on, and off, disconnected and re-connected cables, nothing works, they just don't appear!
Any ideas?
Thanks
Douglas

Maybe the following will help....
Thought you could use this info about getting FireWire to work!
First, you should always Repair Permissions in Disk Utility before and after any update; I would do that now. If you installed your update with FireWire plugged in, your Mac may not recognize it anymore.
Try resetting your FireWire ports by disconnecting all FW devices, shut down your Mac and unplug it from AC power (wall socket) for 30 minutes. plug it back in and try FW.
If that didn't work, download the combo update from this site (yours may be corrupt), not Software Update, disconnect all firewire + USB devices except keyboard + mouse, Repair Permissions, re-install update, Repair Permissions again + try.
If that still didn't get it Zap the PRAM. While restarting Mac hold down the following key combo Command-Option-P-R. Keep holding those keys down till you hear the second start-up chime, then release.
For those of you with Macs that are not PowerBooks or iBooks, a bad internal PRAM battery can cause FireWire to not be recognized, so make sure it's good! Also, here is Apple KB HT1317 on getting FireWire to work.
Here's another Fw Faq.

External Hard Drive not recognised on Intel but is on G4 iBook

Suddenly yesterday my iMac 5,1 running 10.6.8 stopped seeing the Time Machine External Hard Drive. The warning was that it had been disconnected not ejected properly,which I wasn't aware of. I couldn't afterwards get my iMac 7,1 running 10.9.2 to recognise it either. I tried Disk Utility verifying and repairing on both computers. Wouldn't finish, said needed backing up and re-formatting. It wouldn't erase on either because it couldn't be unmounted when it wasn't showing as mounted in the first place. Most of the data were backed up elsewhere and there was a recently used Time Machine I could put in its place.
Then I plugged it into my ancient G4 iBook running 10.4.11 and there it was on the screen with the contents accessible. I've tried verifying and repairing it there but either it's very slow or not really happening at all.
So what's going on? Ideally I'd like to copy the contents over to another drive but will have to get one first, then reformat somehow. I can imagine my G4 iBook will struggle with that. I've reconnected to the iMac 5,1 but it's still not showing there.

Well, this is embarrassing. A suggestion from an older thread on Macrumors.com called "Hard Drive does not appear in Finder / Desktop", solved this problem. Simply drag the missing drive icon from the desktop to Finder! Perseverance and different search wording AND reading a lot of stuff pays off.
If other's problem is not solved with this fix, you might benefit from this 10.5-based thread. They also mention an Apple 10.5 fix. Both URL's below.
The op's problem was that the drive did not appear in Finder OR the desktop but was operational. There was a lot of in-depth information with this fix embedded.
Thanks for the interest and suggestions.

External Hard Drive not recognised after horrible crash and reformat.

There's yet another problem with my MBP.
First of all this happened: http://discussions.apple.com/thread.jspa?threadID=969838&tstart=0
Since I got it fixed I bought a 500GB Freecom external Hard-drive and used it to back up all my stuff. It was a case of plugging it into the USB port and it mounted on the desktop. I've had it for about a month.
I've only just got my MBP back from getting the keyboard replaced, then on Saturday night it crashed. And kept crashing. Then it wouldn't boot. Then it crashed when booting. Then it took me to a command prompt. I reset all the parameters laid out in the troubleshooting guide. I managed to boot in safe mode, but my Freecom drive wouldn't mount anymore. But it kept crashing and crashing. I finally managed to boot from the installation CD and I reformatted the drive and installed OS X (Tiger) afresh. But now my Freecom drive won't show up on the desktop at all!
I ran a Hard Ware test after the reformat, and the code 4MEM/2/40000000 came up, then again, 1FCA8574, then 41530574.
When I had the Freecom plugged in it would show in System profiler but not mounted on the desktop.
What is wrong? I am really annoyed because my Warranty ran out yesterday and I'm only after getting it back from Apple to get the keyboard replaced!
Please help!

External hard drive not found anymore after wrong disconnection?

First time there was no problem and used external hd. After disconnecting the wrong way the mac can't recognise the exteranl HD anymore.
On my other pc it works fine. What happend and how to restore?
Dirk

have you shut down or restarted your computer since last you pulled out the hard drive?
are you connecting it via firewire or usb
go into disk utility when you have your HD plugged in and you will see it there, right click it and hit mount. it should come up.
if you are using firewire, or usb, you might want to not just pull them out without first ejecting it. I've heard, specifically with firewire, that this could fry your whole logic board.

I upgraded my imac to OS Mountain Lion and now the Seagate Goflex external HDD is not recognised

I upgraded the iMac to Mountain Lion and it does not recognize the Seagate Goflex External HDD that I was working from earlier. I do not want to buy a special program since the Goflex HDD was working on both mac and Windows without any problems before the upgrade. The Goflex HDD is still working on my Macbook pro so there is no problem in the HDD. Is there something that needs to be activated... Please help

A bit more info for those of you reading this.... the problem seemed to be in iTunes. For each connected device , if I clicked on the Photo option I could no longer select the second radio button for limiting the photos by Events, Albums, etc. It was an all or nothing deal. But selecting all would cause the error.
So I had read the other forum posts about the "&" symbol being the cause of the problem. I went through iPhoto and made all of the changes. It did not work. I then looked at iTunes, using the AlbumData2.xml file listed in the other forums as a reference. I found one album with the "&". I edited that one. Still would not work. So then I spent 3 hours on the phone with AppleCare last week. I talked with 4 different advisors. None of them had heard about the "&" error from the forums. We tried everything in iPhoto including repair and rebuild. Finally we created a whole new library and reimported my master photos from my original one. Using this option would allow me to now check off that radio button in iTunes. BUT... I now lost all of my albums and events and would need to rebuid them. I was not happy. They agreed and we set up time to talk this week.
So today I talked with AppleCare again. They now have more info and said the problem has to do with iTunes and the new iPhoto 9.4. It does not like the "&" symbol anywhere in either iPhoto or iTunes. So they now have me going through everything in my iTunes library. Genre is OK but any other item cannot have " & ". I have several dozen to edit and will do it over the weekend and then restore my original iPhoto Library and see if I can finally get it all to sync. I will let you know how I make out, but apparently you need to eliminate " & " from every entry in iTunes and iPhoto.
Quality control is not up to par with Apple these days.

External WD drive not recognise by Time Machine

i have a WD drive that i use to back up my macbook pro, last update it was an error and update was not completed, then it didn't allow me to properly eject the drive, so I just disconnect it, now when i plug it in mac doesn't recognise the disk, i have already 500giga back up there, any suggestion of what can i do?

Thanks
it was in disk utility but it says it cannot be repair, and I have all my backup sin this disk (500g)? can I still do something or should I take it an IT guy?
The volume Time Machine Backups could not be verified completely.Volume repair complete.Updating boot support partitions for the volume as required.Error: Disk Utility can’t repair this disk. Back up as many of your files as possible, reformat the disk, and restore your backed-up files.

External Hard Drive Not Working Anymore

I got a little hard drive which has two partitions formated with NTFS and the other one for Mac (forgot what it was called...HFS or so?).
Well..none of those partitions work like they are supposed to. When I connect the hard drive it shows me both partitions mounted but when I try to unmount them it just won't work. It says it is in use but I am sure that they are not. I tried formating them in Disk Utility which didn't work cause it could not unmount the drive.
So what I'm trying to find is a way to make my external hard drive usable but I just don't know how and what to use. I'm not very familiar with disk repair utilities.
Some other problems are that I can't copy anything onto/from the hard drive or i doesn't show me anything in Finder eventhough there's a bunch of stuff on there.
I don't know if you need this info but I'm on a MacBook Pro running 10.5.4 and the hard drive is Mac-compatible.
Every help is appreciated!

If you don't have any information on the drive which you need, try this:
* Boot from the Leopard DVD.
* Chose Disk Utility from the menu.
* In the list, you'll get two listings for your external drive. Choose one at the top which isn't indented that lists the drive size first (for example, 298.1 GB WD 3200JS External Media).
* Click the Erase tab.
* Set format to Mac OS X Extended (Journaled)
* Click Security Options and select "Zero Out Data"
* Click Erase...
This should hopefully wipe the drive completely clean, erasing the other partitions and making sure the the whole disk is writable. If this doesn't work, I would suspect a hardware issue with the drive. Once this is done, you can repartition the drive as needed.
